HERBERT E. WHITE, OF YOUNGSTOWN, OHIO, ASSIGNOR TO THE TRUCSON STEEL COMPANY, OF YOUNGSTOWN, OHIO, .A CORPORATION OF OHIO.

BOTTOM-HUNG-SASH CONSTRUCTION.

Application filed February 10, 1921.

T o all whom t may concern:

`Be it known that I, HERBERT E. W'Hrrn, citizen of the United States, residing at Youngstown, in the county of Mahoning and tate of Ohio, have invented certa-in new and useful Improvement. in Bottom- Hung-Sash Constructions, of which the following is a specification.

This invention relates to an improvement in Ventilating sash construction for buildings, and has particular reference to a bottom hung sash unit yhaving an automatic weathering' jointbetween the top edge thereof and the framework of the building.

Accordingly a primary object o-f the invention is to provide in combination with the desirable feature of a bottom hung sash unit, a novel weathering member cooperating with the upper or swinging edge thereof in such a manner as to pro-vide a weathertight joint for the top of the sash unit while at'the same time not interfering with the adjustment of the latter for Ventilating purposes. In that connection, a further object of the invention is to provide in combination with` the bottom hung sash unit, a weathering member' which will be automatically shifted to an out of the way position without the aid of mechanical devicesto permit the sash to swing freely outward,

' and likewise uponits return to a closed position, it may be automatically engaged with the weathering member to automatically form the joint.

It is to be noted that heretofore it h-as been impractical to effectually utilize a bottom hung sash construction because ofthe fact that a satisfactory weather-tight joint could notbe formed between the upper edge of the sash and the framework of the building, but the present invention meets the requirements in. that respect and makes it possible to use a sash of the bottom hung type with' the minimum of operating devices, thereby not only simplifying the mechanism involved but at the same time reducing the cost of installation and adding materially to the reliability and usefulness of the device because of its simplicity of design and arrangement.

Vith the above and other objects in view, which will more readily appear as the nature of the invention is better understood, the same consists in the novel construction, combination and arrangement of parts here- Seral No. 443,951.

inafter more fully described, illustrated and claimed.

A preferred and practical embodiment of the invention is shown in the accompanying drawing, in which The ligure is a vertical sectional view of a bottom hung sash unit showing the sash in its closed position in full lines and in its open position in dotted lines, the relative position of the canopy or weathering strip being also shown.

In large buildings such as foundries, glass works, forge shops and the like requiring extensive ventilation, a sash construction of the bottomhung type, such for example as that shown in my copending application filed February l0, 1921, Serial No. 443,950 is very desirable.

In the construction of the invention referred to in the above application, the important feature of providing an adequate weather-tight joint at the top edge of the sash is provided for by means of a hand or mechanically operated weathering element, but the present construction has in view a simplified form of construction wherein the weathering unit or canopy is operated automatically by the movement of the bottoni hung sash, and by gravity.

Accordingly, as will be observed from the accompanying illustration, it is proposed to mount the bottom hung sash unit S upon the supporting hinge member l carried by one of the upright frame members of the building structure whereby it may be swung erating connection O tov permit its upper frame member 2 to move toward and from its former position to provide a variable discharge passage or Ventilating outlet.

When the said bottom hung sash is in its normal closed position, its upper edge 2 is yweather sealed by a novel weathering strip unit designated in its entirety as 3. This novel unit is pivotally suspended in a suitable position above the top edge of the sash whereby it may freely engage and disengage with the sash to provide kan overlapping weather-tight joint, and although this unit may be embodied in various structural forms, a preferred and practical typethereof is shown in the accompanying drawing, wherein it will be observed that the same primarily consists of the continuous weathering strip or plate 4 provided at its upper end with an outwardly turned hook flange 5 adapted to engage in the angle or groove of the continuous supporting member 6 thereby constituting a hinge for permittm the weathering strip to rock or swing Wit the movement of the sash. t

The lower edge portion of the weathering strip 4lis preferably bent inwardly as at 7 to provide a sealing edge adapted to engage with the outer flange of' the channel member 2, and the inner face of said strip preferably carries a hood forming angle plate 8 having the attaching flange portion 9 and the depending abutment fla-nge portion l() for engaging with the opposite flange of the channel member 2 of the sash. The hood plate `8 with its depending abut# ment flange 10 cooperates with the sealing fiange 7 of the weathering strip to provide an effective hood or bonnet for receiving the entire upper edge of the sash when the latter is in its upright or closed position. The said channel member 2 of the sash has a relatively snug fit within the mouth of the hood, and yet has ample operating clearance to become disengaged therefrom upon the outward movement of the sash. The upper portion of the weathering strip 4 is preferably provided with a counterweight receiving chair 12 for receiving a suitable weight which will have a tendency to rotate the entire weathering unit from the full line position shown to the dotted line position, so as to yhold and maintain the strip in an outward position to receive` the upper edge of the sash when the latter swings from an open to a closed position.

By reference to the mannerpof operation and functioning of the parts, it will be observed that when the sash and weathering unit are in the full line position shown in the illustration, the weather-tight connection between the sash and the canopy or weathering strip is complete. However, when it is desired to open the sash for ventilating purposes, the operating mechanism O comes into play to permit the upper edge of the sash to swing outwardly to the dotted line position, whereby the movement of the sash will carry the weathering `unit to the dotted line vposition shown by reason of the channel member 2 engaging with the sealing liange 7 along the bottom edge of the weathering strip. Upon the return movement of the sash, the opposite flange of the channel 2 will strike against the abutment flange 10y of the hood yto thereby rock the entire weathering unit back into its full line position, against the resistance of the counterw'eight within the chair 12. 'It will, therefore, be, apparent that the operation of the weathering unit or canopy is entirely automatic. l j

.Without further description, it is thought that the features and advantages of the invention will be readily apparent and it will of course be understood that changes in the form, proportion and minor details of construction maybe. resorted to without departing from the spirit of the invention or .scope of the appended claims.
